Jet engines do not spin too fast for electric starters. Smaller jet engines use electric starters. In most cases, they use a combined starter/generator which drives the engine during start and is driven by the engine when operating as a generator.
Larger jet engines could use electric starters but they would be larger and heavier than pnuematic starters so pnuematic starters are used.
